From publisher blurb:
As security for hire, the PCs should expect gravitational anomalies and roving space goblins. Those are just the standard occupational hazards. But the icy world of Muinmos 6 was supposed to be uninhabited, and the distress signal coming from its surface shouldn't be possible. Conspiracy, corruption, and kidnapped aliens can mean only one thing: this simple scientific mission is going to be anything but simple.
Star System Sets offer new planets to explore, dangers to overcome, lifeforms to study, and cultures to document. Modular enough for any campaign, each double-sided card presents a complete ruleset for ease of reference, allowing GMs to fill in the blank spots on their star charts.
Card types include Race, Planet, Character Options, Equipment, Monsters, and Mini-Adventure. Each set is available à la carte or as a six-card bundle.
